This invention relates to gasoline reserve supply apparatus' for automobiles, motor boats, and the like'and has forv its primary object-the reservation within the usualV line supply tank of a-ll'tli'eV gasoline below a predetermined level as a reserve f supply.,v

with provisions whereby an alarm* will be given when such level of the gasoline in the tan-k is reached, after which the reservek supply can be utilized in drivingnthe automobilevtov a filling station. Y

Another object of this inventionisto arrange the suction pipe leading from the gasoline Vtank to the carburetor sol that gasoline is 'at all timesdrawnoifV from the bottom of 'theta'nln therebyprevent-ing the accumulation of water or fuel of low gravity at the bottom of the tank to render the reserve supply of inferior quality to rthe main supply of gasoline.

A further object'of my invention is the provision of simple 'and comparatively in expensive means for' preventing the'gc'on?v sumption of the full supply of fuel by the engine without irst requiring vthe driver tooperate the mechanism to perm-it'the use of the reserve supply and thereby calling hisL attention to the fact that it is' necessary to obtain a: vfresh supply of gasoline, such mechanism being readily operated' by .the driver without leaving his seat and com'- prising the closingA of an air-filled' bypass pipe to permit the resumption offu'ell' feed? ing through the saine supply' pipe.

rlhe above and otherobj'ects of myf'i-nven-tion will be apparent from the following description wherein* reference is made to the accompanying drawings illustrating preferred embodiments of my invention, and wherein similar reference numerals des ignate similar parts throughout the several views. Y

In the drawings:

Fig. 1 is a diagrammatic view, with parts in section, showing my reserve sup ily apparatus arranged so that the reserve supply can be brought into use by turning a valve mounted on the dashboard of an automobile.

Fig. 2 isa side elevation'of such valve with the dashboard shown in section, and

3 is a detail front view of the dashboard and valve.

This application is a division of my application tiled Gctober 24, 1921, Serial No.

510,137, now Patent No. 1,461,305, and reclosed but not claimed in such parent appli catio The claimed disclosurelierein utilizes'a feed pipe 11C divided longitudinally into compartments,through one of which, as for example that shown on the right side in!A Fig. 1, liquid gasoline is drawn into thev pipe line 8 secured at its rear extremity upon a T shaped valve casing T and lead-r ingto a valve casing 29 mounted upon the dashboard 30 of an automobileand thence: to

mobile in the usual manner. YThe valve casirifg.291 is herein illustrated as substain" tially T shaped with three'piassagewaysra'- ing to the vacuum tank or carburetor with the passageway 32'at lthe right side oft-he valve casing 29'. A port llic'is positioned in the opposite compartment of the feed pipe 11c at any desired height above theA bottom 'of they tank 5c and an up'perlpo'rt 15'C conf nects this compartment with the bypass pipe 331 connecting the' left handlportion's of the T shaped' valvecasings 7 andi 29.

f The val-ve 34is suitably seated in the cas-A in'g 29 and provided with three radial passages adaptedto connect with the passageways 31,. 32 andl 33 when in the position shown in Fig. 1. This position is the one maintained whenY the main supplyof gasof line Ais being drawn from the tank 5. Ink

' operation the l'iqL'i-idgasolin'e is drawn' upward-ly' from adjacent the bot-tomi the tank 5c through the right hand compartment of the feed pipe 11c into the pipe line 8, passageways 31 and 32 of the valve casing 29, into the continuation 8d of the pipe line leading to the Vacuum tank or carburetor.

This action continues kuntil the liquid level falls below the port in the opposite compartment of the feed pipe 11", whereupon air is drawn through such compartment into the bypass pipe 33 and the passageway 32 of the valve casing 29, breaking the vacuum and thereby stopping the flow of the liquid gasoline. The engine will thereupon give warning, as hereinbefore described,

that the fuel supply is low. The. valve 34L canthen be rotated by grasping the knob 35 thereofv and turning it through a quarter revolution, thereby moving the radial pasiio .sage of the valve 34 opening into the bypass 33, as shown in Fig. l, into position to open into the central passageway 31 of the valve casing 29, and simultaneously swinging the passage formerly opening into the central passage 3l into position to register with the right hand passageway 32. The left hand passageway 33 is closed by this movement of the valve 34, thereby preventing the entrance of air to the pipe line 8d to further prevent the formation of a vacuum to draw up liquid fuel.

In Fig. 3, I have illustrated a dial-adapted to be mounted on the dashboard 3() with a pointer 36 mounted on the stem of the Valve 34 to show whether the main or reserve supply of gasoline is being drawn upon.

IVhile it will be apparent that the illustrated embodiments of my invention herein disclosed are well calculated to adequately fulfill the objects and advantages primarily stated, it is to be understood that the invention is susceptible to variation, modification and change within the spirit and scope of the subjoined claims.

I-Iaving described my invention, I claiml. In a device of the character described, a tank adapted to contain liquid fuel, a feed pipe mounted therein and extending from .adjacent the bottom of the tank to a position above the tank, said feed pipe being divided longitudinally into compartments, a valve casing mountedon the vehicle in a position convenient to the drivers seat, a pipe line leading from one compartment to the valve casing, a bypass pipe leading from the other compartment to the valve casing, a pipe connecting the valve casing to the carburetor of the engine, and an. apertured valve mounted in said casing and movable to positions connecting the bypass pipe with or closing it off from said pipe between the valve casing and carburetor.

' 2. In a device of the character described, a tank adapted to contain fuel, a feed pipe mounted therein and extending from adjacent the bottom of the tank to a position above the tank, said feed pipe being longitudinally divided into compartments, said compartments having upper ports exterior of the tank and one of said compartments also having a lower port therein spaced a predetermined distance from the bottom of the tank, a pipe line connecting the other compartment with the carburetor of the engine, a valve casing adapted to be mounted on the dash-board of a vehicle arranged intermediate the ends of said pipe line, a bypass pipe connect-ing the compartment having upper and lower ports with said valve casing, and a valve in said casing with passageways therein arranged when in V one position to connect said bypass pipe with said pipe line, and rotatable to a position closing said bypass pipe.

3. In a device of the character described, a tank adapted to contain fuel, a feed pipe mounted therein and extending from adjacent the bottom of the tank to a. position above the tank, said feed pipe being longitudinally divided into compartments, said compartments having upper ports exterior of the tank and one of said compartments also having a lower port therein spaced a predetermined distance from the bottom of the tank, a pipe line connecting the other compartment with the carburetor of the engine, a valve casing adapted to be mounted on the dash-board of a vehicle arranged intermediate the ends of said pipe line, a bypass pipe connecting the compartment having upper and lower ports with said valve casing, a valve in said casing with passageways thereinY arranged when in one position to connect said bypass pipe with said pipe line, and rotatable to a position closing said bypass pipe, and indicating means on said valve for visually indicating in which position the passageways of the valve are placed.
